To all whom z't may concern:

Be. it knownthat 1, JOHN G. CALLAN, a citizen of the United States, residing at Lynn, county of Essex, State of Massachusetts, have invented certain new and useful Improvements in Winding-Machines, of

in winding resistance coils, electromagnet coils, the coils used in electrical measuring mstruments and the like, but is particularly designed with adjust- I able parts, many of them 0 erated automatically, to adapt the mac ine for forming more complicated structures such, for instance, as the small armatures used in electric meters of the motor type. These armatures consist of a plurality of coils each consisting of a definite number of convolutions of very small insulated wire similarly disposed about a light form of wood, aper, nonmagnetic sheet-metal, or of fusib ematerial which is afterwards melted out.

The object of my invention is to rovide a i winding machine which may be a justed to wind articles varying widely in construction and in which many of the necessary operations are performed automatically so that the outputer operator is greatly increased and the finis ed products are more'uniform. Though particularly designed for winding coils of wire for use in electrical apparatus it will be readily understood that theinvention I is in no way limited to such uses.

The novel features of my invention will be definitely indicated in the claims appended hereto; the details of construction and the mode of operation of my improved winding machine will be better understood by reference to the following description taken in connection with the accompanying drawings which show one embodiment of my invention. I In the drawings, Figures 1 and 1 show a I front View'of the machine, Fig. 1 showing in full linesi-portions of the machine above.

those shown-in 'Fi .41 and in dotted lines ortion of the machine shown in Fig. 1, brodren away in part; Fig. 3 is a similar view ofthe other side of the machine; Fig. 4 is a back view; Fig. 5 is a top view, some of the parts and guide-positioning mechanism; Fig. 10 is a section on line 10 10 of Fig. 3; Fig. 11 is a section on line 11 11 of Fig. 3; Fig. 12 is a sec-' tion on line 12 12 of Fig. 2; Fig. 13 is an elevation of a type of armature'which may be wound on the machine Fig. 14 shows one coil of thearmature shown in Fig. 13, broken away in part to show the cross-section of the coil; and Fig. 15 is a diagram of the circuits.

Referring to the drawings, 1 indicates a table on which the machine is mounted, and 2 the driveshaft of the machine to which rotary motion is communicated by a belt from any suitable source, of power or by an electric motor supported beneaththe table with its shaft in a vertical position and coupled directly to shaft 2. Near the upper end of the shaft 2 is a friction roller 3 which engages-a friction roller 4 on a shaft 5 which. carries at its'opposite end friction rollers 6 and 21, Fig. 5.

Mounted in suitable bearings in the frame 7 of the machine arallel to shaft 5 isa shaft 8, on one end of wfnch is a fly-wheel 9; on the other end of shaft 8 is a supporting member or holder to support the. material during the winding operation or to hold a form or armature frame on which a plurality of coils are to be wound. The particular design of this holder may vary widely with the different articles Which are to be wound; for some purposes I prefer to use a fork as shown in Fig. 1. Mounted on shaft 8 is a friction roller 11 inclosed by a casing 11, which is adapted to be engaged by the roller 6 to communicate rotary motion from shaft 5 to shaft 8.

In order to move the friction roller -6 into and out of engagement with roller 11, the end of shaft 5 is. supported by a strip of springmetal 12 as best shown in Fig. 2, and means are provided for moving the strip and with it the end of shaft 5 and the roller 6 toward and away from roller 11. The lower end of the flexible strip 12 is fastened in a block 13 on the table 1, and an arm 14 carried by, a shaft 15 has a forked end which, straddles strip 12. Shaft 15 is mounted in suitable bearings and is provided with an arm 16 which extends forward and is rovided at its forward end with jaws 17, as est shown in Figs. 2 and 12.

Mounted in a bearing in the front of the frame 7 is a shaft 18 provided with a handle 19, and on the inner end of this shaft is a pin 20, Fig. 12, eccentrically disposed and ex tending between the jaws 17 in the arm 16.

'Thus by turning handle 19 a quarter revolutionin either direction the arm-.16 is moved up or down by pin 20,-rocking shaft 15 in its bearings and moving the arm 14, the strip 12 and shaft 5 either forward or backward. The forward movement of strip 12 brings roller 6 into engagement with roller 11 and thus drives the supporting member on whic the coil is wound. A- backward moveme t of strip 12 carries roller 21 which is keyed on the shaft 5 into engagement with a wheel .22

carried by a shaft 23 (Fig. 5). This latter shaft is supported in bearings in arms 24 on the frame 7 in such a manner as to permit it to be readily removed and carries the reel of wire or other material from which the coil is wound. A thumb-nut 25 is adjustable on shaft23 and may be screwed up against the,

reel in order to hold it tight on the shaft and thus cause it to rotate with the wheel 22. When the friction roller 6 is in engagement with roller 11 and thus driving the member 10 towind on the turns of wire, the roller 21' is out of engagement with the wheel 22 and the'shaft 23 rotates freely except for certain braking devices which will be more fully described hereafter;- but when the strip 12 is moved backward by arm 14 roller 6 disengages roller 11 and roller 21 engages wheel 22. .The shaft 8 and the form carried thereby are thus freeto rotate and the wheel 22- and shaft23 are driven by the frictionroller 21 in 'a direction to wind the wire upon the reel carried by shaft 23, that is, in a direction to draw, the wire ofhfrom the form carried by the fork .10 on which it had been wound.

When the handle 19 is turned one-quarter of a revolution to connect shaft 5 in driving relation to 'shaft 8 it is held in that position for a definite period of operation. The means for accomplishing this consists of a latch controlled by an electromagnet. .On the shaft '18, to which thehandle 19 is fastened, is a crank (Fig. 1) which is connected by a link 76 to a stiff spring 77 mounted on the bottom of the table 1. Also secured on the bottom of the table is an electromagnet 78 provided with a spring-retracted armature 79 which is shaped so as to form a latch for the spring 77 as shown in Figs. 1 and 4. 'Thus when the handle isturned, spring 77 is drawn up until it catches over the edge of the armature 79 and shaft 18 is held by friction in its bearing in this position against the tension of the spring strip 12. hen circuit through the coils of magnet 78 is closed as will be hereafter explained, the magnet is energized, armature79 is attracted and spring 77 released 1 and the latter turns shaft 18 to its normal po- .ver 30.

sionof the .wire increases due to the braking effect of lever 30 and wire 31 or to the way the wire is woundon the reel or to any other causes, the roller 26 is drawn down-by the wire itself and the spring 36 put under tenon the wheel.

sition in which shaft 5 is disconnected from both shafts 8 and 23. The wire from the reel carried by shaft 23 passes up over a spring-supported roller 26 (Fig. 5), down over a roller 27 carried by a s ring-arm 27 supported on the arm 24, then own over two guide-rollers 28 and 28 carried on the ends of apivotally-supported leaf spring 29, and then up to the form on fork 1-0 where it is wound on in the prop er relation; It

will. be seen that'the various guide-rollers over which the wire passes are all spring-sup ported and will therefore yield and tend to equalize the tension of the wire that is wound to form a coil. In order to insure thisequality of tension I employ a tension equalizing device responsive to the. tension of the wire itself. sion equalizing devices may be provided for this purpose; in the present instance I have illustrated a simple mechanical device con-.

sisting of a brake acting on the shaft 23 or the reel of wire carried thereby and means for varying the effect of this brake as the tension of the wire varies. The wheel 22 on the shaft 23 is provided with aperipheral groove, and below this wheel is pivotally mounted a brake-lever'30 carrying a wire 31 as shown in Fig. '1. A spring 33 acts on the brake-lever 30 in a direction to force it and wire 31 forward into the groove on the wheel 22. Bigidly supported on the top of frame 7 and. extending upward therefrom, is a standard 35 in the end of which is pivotally mounted a leaf-spring 36 carrying the guide-roller 26.

Connected to spring '36 is a downwardly-em tending rod 37 which is connected by an ad Any one of a number of forms of tenj ustable link 39 to the upper end of brake-le- It will thus be seen that as the tension, this tends to move rod 37 to the right in Fig. 1 and rod 37 carries with it the brake lever 30 and wire 31 against the tension of spring 33 thus decreasing the braking ,ef-

fect on the wheel 22 and allowing the wire to be drawn from the reel more freely. As the tension of the wire decreases, arm 36 straightens out, and spring 33 pulls'brtike-leVer, 30 up against wheel22 to increase its braking effect The tension of the wire is thus axial movement in bearings in the frame 7. Rigidly secured to shaft-40 is an arm 43 to which is pivotally connected a guide-positioning rod 44 which also extends through a bearing in the frame 7 and is axially movable. Thus by reciprocating the rod 44, spring 29 is rocked on its pivot and the rollers 28, 2S are moved from side to side to guide the wire as it is wound on the form and cause it' to .wind a plurality of layers of any desired width one on top of another; the speed at which rod 44 is moved may be such that successive turns are wound side by side to form an even regular layer and the extent of the .movement of rod 44' determines the width of the several layers. It is sometimes desired to wind a coil of a plurality of layers and have the successive layers increase or decrease in width; this can be accomplished on the machine automatically by varying the throw of the rod 44, that is, by increasing or narrowing the limits between which the rod is'rcciprocated as the winding progresses. Such a coil is shown in Fig. 14; the width of the first layer of turns is small and in the succeeding layers steadily increases until the last is reached; or the coil may be wound in the reverse order by starting with a layer of the maximum width and decreasing with each succeeding layer. In winding an armature such as that shown in Fig. 13 a coil similar to that shown in Fig. 14 would be used the particular cross-section of the coil being desired in order thatthe coils will lie close. to the shaft as compactly as possible atthetop and bottom of the armature where they cross each other.

The mechanism for causing the axial reciprocatory movement of rod 44 will now be described. ()n the shaft 8 and within the frame 7 is. a worm 45 (Figs. 6, 8 and 9) with' which meshes a worm-wheel 46, mounted on a shaft 47 carrying a cam 48. Cooperating with cam 48 is a lever 49, on the end of which is a roller 49 bearing on the cam surface; a spring 50 having one end secured to lever 49 and the other end to a post 50! holds the roller in engagement with the cam. The end of lever 49 is pivotally connected to a link 51 which is pivoted on a post 52 integral with the plate 52 secured to the face-plate of the machine. The link 51 is provided with a hooked arm 53 on which a sleeve 54 is slidably mounted, and the inner end of rod 44 is pivotally connected to this sleeve. It will thus be seen that as the cam 48-is rotated the link 51 is rocked on its pivot 52 thus reciproeating the rod 44. So long as the position of the sleeve 54 on the hooked end of link 51 remains thesame the rod 44 will be moved back and forth between the same limits, and the layers of turns of wire wound by the machine will be of equal width.v In order to automatically increase ordecrease the width of the several layers, a variable throw mechanism is employed by which the position of wind such a pair of parallel coils the operator sleeve 54 on the hooked end of link 51 is au-- tomatically changed so that the reciprocatory movement of rod-44 is steadily increased or decreased. This mechanism consists of a cam 55 mounted on a shaft 56 extending through a sleeve 86 on which is mounted a ver 50, and at the other to post 50'. A link 62 is pivotally connected to the end of lever 59 and to the end of rod 44, so that as cam 55 is rotated the lever 59 is turned on its pivot and operates to move the end of rod 44 up and down on the hooked end 53 of link 51. The leverage of the link 51 on the rod 44 may thus be changed contimumsly and automatically, effecting a corresponding change in the reciprocatory movementof rod 44.

In some cases in winding armatures for meters of the motor type it is desired to wind a number of layers of wire each consisting of a plurality of turns around a suitable form and close to a central shaft or opening or in a groove in the form and then wind a similar coil in continuation of the first coil and parallel thereto but on the opposite side of the shaft or opening or in' another groove. Ordinarily the layers of turns in these coils are of equal width so the variable throw mechanism governed by cam 55 is not used though of course it can be if desired. Some additional mechanism is required however. to move the guide-roller 2S and the supporting member relatively after the first coil is wound to bring the parts to the position necessary for. winding the second coil. I. accomplish this by moving the rod 42 which carries the guide-rollers 28 and 28. The guide-holding rod 42 extends through the frame 7 and on the left side of the frame is provided with a slot into which a pin (53 extends to permit axial movement of the rod but prevent turning. \Vithin the frame 7 a coiled spring 64 surrounds the rod, as shown in Fig.4, and urges the rod in a direction to move the guide-rollers 2H, 28 away from the frame. On the end of rod 42 opposite that which carries the guiderollers is a thumbnut 65 held in any position to which it is adjusted by a lock nut 66. 3

- At the back of the machine are standards 67 (Figs. 3, 4 and 10) in which a sleeve (38 is pivoted and rotatable within this sleeve is a rod 69 which for a portion of its length is cut down to a rectangular cross-section and is adapted to fit between the thumb-nut 65 and a boss 70 on the frame 7 through which the rod 42 extends as shown in Fig. H. To

- machine will be of equal width.

.may. be inserted in a hole of the disk 87 in laces the rod 69 between thuinb-nut and oss as shown in Figs. 1 and 11 by grasping the nut' 65 and pulling it and the rod 42 to which it is secured axially to the right far enough to permit the entrance of the rod 69 between the thumb-nut and boss; when the number of turns desired for the first coil have been wound rod 69 is automatically removed from between nut 65 and, boss 70 and spring 64 pushes the guide-holding rod 42 axially to shift the guide roller 28 to .the proper JOSitiOn for windin the second coil. The

the armature ofa'n electromagnet 81.

Thus when circuit is closed through the coils of magnet 81 the magnet is energized, arma-' ture 80 is attracted, latch 74 releases p ro ec' tion 73., and spring 71 turns rod 69 on its axis about degrees thereby moving the rod from the position shown in Fig. 11 with its- 'rectangular position between nut 65 and boss 70 to a pos1t1on in which the longer side of the rectangular portion of rod 69 rests upon the upper surface of the nut 65 and boss- 70; as soon as therod is removed from between nut 65 and boss 7 0, s ring 64 pushes guideholding rod 44 axial y toward the left in Fig; 1 until the opposed faces of nut 65 and boss 7 engage and thus prevent further axial movement of the rod. When the latch 74 is holding the projection73 an upwardlyextending portion 74 thereon is in engagement with a spring contact 82 mounted on'a block of insulating material 83, but when the latch releases projection 73 and magnet 81 is decnergized. a spring 84 pulls the latch forward away from spring contact 82 and into engagement with the head of a screw 85, thus breaking the circuit through contact and establishing a new circuit through contact 85.

Splined to the forward end of the shaft 56 v is a disk 8'7 (Fig. 9) in which are a number of holes (Fig. 7) to receive pins 88. The end of shaft 56 is threaded to receive a hand-nut 89 which may be turned to press a spring washer 99 down upon the disk 87 to force it against the sleeve 86 and thus cause shaft 56 to ro tate with sleeve 86. Secured on the face plate of the machine is an arm 91 which is engaged by one of the pins 88 to arrest the disk 87 and thus hold shaft 56 stationary. When this occurs the variable throw mechanism actuated by cam 55 isrendered inopcrative and the layers of turns wound by the The pin 88 such relation that the variable throw mechanism will operatefor a definite portion of the windin'g operation and will then be ren- 'dered inoperative or in a positionto render the mechanism inoperative throughout the winding operation. For convenience in o crating the machine a second pin 88 may e inserted in one ofthe holes in disk 87 to limit the backward movement of disk 87 in adjustin the machine when a number of similar coils are to be wound.

In order that. a definite number of turns may be wound in each coil I provide a counting device arranged so as to stop the winding op'erationafter the desired number of turns have been wound. Secured'on the back of metal pins 94 may be inserted to make electrical connection, to the conducting rings. On the shaft 47 is a metallic arm 95 adapted to engage a pin in an opening of the upper circle and secured on sleeve 86 is an arm carrying a brush 96 006 crating with the pins in the openings of t e lower circle. The gearing upon shaft 47 and sleeve 86 for convenience should have a-ratio of reduction of 10. to '1 so that arm 95 would make a complete revolution while brush 96 is making one-tenth of a revolution and there should be ten holes leading to each ofthe rings 92 and 93 spaced at equal distances apart. In 0 crating the machine a pin. is inserted in t e holein the lower ring corresponding to the number of hundreds of turns and a pin in the hole in the upper ring corresponding to the additional number of tens of turns, and the machine. is then started. When the desired number of turns have been wound the brush 96 and the arm 95 will be in'contact with the two pins as, will be readily understood, completing a circuit from ring 92, to arm 95,'t0

the frame of the-machine, to brush 96 and to the lower ring This circuit is completed through the'coi l 78 of the release magnet which as above explained disconnects the drive shaft-from the shaft 8. 7

The operation of the machine as thusconstructed will be readily understood. The form on which the coil is to be wound is. inserted upon fork 10; a reel of wire is mounted on the shaft28 and the thumb-nut 25 is screwedup on the reel to hold it tight upon the shaft. The wire from the reel is led up over roller 26, down over roller 27, and over the guiderollers 28, 28 to the form. Pins are inserted in the rings 92 and 93 .in the .posi. tions corresponding to the number of turns it is desired to wind on the form. Handle 19 is then moved 9() degrees to the right, thus moving strip 12, shaft 5 and roller 6 forward, and connectingrolle'r 6 in driving relation to shaft 8; the su porting member is thus rotated'drawing t e wire from the reel 23 and winding it up on the member. As the wire is wound on, cam 48 reciprocates the rod 44 and guide 29 so as to lay the turns on in layers, one on top of another. The width of these layers depends upon the position of the cam 55 which may be moved to any position necessary togive the width desired for the several layers by adjusting the disk 87 and inserting a pin 88 therein in a osition toabut against the arm 91 and hol shaft 56 and cam 55 against movement. When operating in this way the spring. contact 74 on the latch 74 which carries armature 80 is in contact with the screw 85 (Fig. 15) and when the arm 95 and brush 96, which are driven from shaft 8 through gears 45, 46, 58. and 57', come in contact with the pins in the-rings 92 and 93 a circuit is closed from a source. of supply 98 to spring 74, contact 85, magnet 78,

rmg 92, arm 95 to the frame of the machine, to brush 96, ring 93 and back to the source 98. Magnet 78 being ener'gize'd'disconnects the drive shaft 5 from the shaft'8 of the supporting member as above described and the winding operation stops. If it is desired toautomatically increase or decrease the width of the layers as the winding progresses, pin- 88 is laced in such a position in disk 87 as will ailow the proper movement of cam 55.

Then as the winding progresses cam 55 is driven from shaft 8 through gears 45, 46, 58, 57, sleeve 86, disk 87, to shaft 56, and cam 55 on shaft 56 moves rod 59 on its pivot and thus shifts the position of the end of rod 44 on the hooked end 53 of link 51. This changes the leverage of lever 51 on rod 44 continuously and automatically so that the 'width of the layers is continually increased.

If the width of the layers is ,to be decreased automatically, cam 55 may be reversed upon shaft 56. Also, pin" 88 may be placed in such a position in disk 87 that the width of thesuccessive layers of turns is increased or decreased during only a ortion of the wind tact 82.

ing operation. If it is esired to wind two coils parallel to each other but laterally displaced and have the second coil a continua tion of the first, the rod 69 is placed by hand between the thumb-nut and boss 70 and is held in this position against the tension of s )ring 71 by the projection 73 catching uner latch 74. In doing this, the spring contact 74 on latch 74 15 carried away from screw 85 and into engagement with the'con A pin is inserted in one of the holes of the lower ring 93, as for instance at 97,

15, in a position corresponding to the number of turns which are to be woundin' the first coil and pins are also inserted in the upper and lower rings in positions corre' spondin to the total number of turns which are to ewourid on the two coils. The machine is then started as before, a coil is turn rod 69 in sleeve 68 and thus withdraw the rectangular portion of the rod from between nut 65 and boss 70 whereupon spring 64 forces the guide-holding'rod 42 to the left in Fig, 1, shifting the guide to the osition for winding the second coil. W hen brush 96 moves off of pin 97 this circuit is opqened and magnet 81 releases armature 8O w ich is drawn byspring 84 to a position in which contact 7 4 is out of engagement with spring arm 82 and in electrical contact withscrew 85. The winding of the second coil progresses until brush 96 and arm 95 engage the pins in the lower and upper rings respectively. Circuit is then closed from the battery through the contact 74", contact 85, magnet 78, to the upper ring, then through arm 95 to the frame of the machine, through brush 96 and ring 93 back .to the battery 98. Magnet 78 being energized attracts its armature, thus releasing spring 77 and the latter -turns shaft 18 and shaft 15 in their bearings thus carrying roller 6 out of engagement with the roller 11.

If for any reason the turns are not laid on properly and it is desired'to wind themoffand back onto the reel, the handle 19 is turned from the running position a half revolution in-the reverse direction. By means of the eccentric pin 20 on the shaft of handle 19 and the arm 16 with which it cooperates, the shaft 15 is turned on its bearings and arm 14 thereon moves spring strip 12 and shaft 5 supported thereon backward, carrying roller 6 away from roller 11 and roller 21 into engagement with wheel 22. The shaft 8 of the supporting member is thus disconnected from the drive shaft and shaft 23 carrying the reel is rotated and draws the wire off.
